We have had a service contract with Stark for several years.  Gives us a reduced rate on semi-annual system check, plus peace of mind knowing they will come out (also at a reduced rate) if we have an emergency need.  Their technicians are always knowledgeable and courteous.  Latest tech, Isaics, was in and out in no time still doing a thorough check with recommendations on needed repairs.We trust Stark and would not think of doing business with anyone but them.
